This is a phase II, randomized, double-blind, placebo-controlled, multi-center study to evaluate the safety, tolerability, and efficacy of adrenocorticotropic hormone (ACTH, Acthar gel) administered as a pulsed regimen consisting of injections on three consecutive days per month in patients with progressive forms of Multiple Sclerosis (MS). Patients will be randomly assigned to either an ACTH arm or a placebo arm. The main hypotheses are that 1) pulsed ACTH will be safe and well-tolerated, and 2) pulsed ACTH will slow progression of clinical and paraclinical measures of MS progression compared to placebo.

Current serious medical condition which may interfere with subject's ability to complete the study, or for which pulsed ACTH therapy is contraindicated or might complicate current therapy (e.g., cancer, severe psychiatric illness, chronic infections, autoimmune disorders)

Treatment with cytotoxic agents (including but not necessarily limited to mitoxantrone, cyclophosphamide, alemtuzumab, or rituximab) within 3 years prior to randomization

Treatment with FDA-approved first-line MS disease-modifying therapies (B-interferon, glatiramer acetate, fingolimod, teriflunomide or dimethyl fumarate) will be permitted, as long as treatment has been ongoing and stable for at least 3 months prior to randomization

Treatment with dalfampridine or compounded 4-aminopyridine (4-AP) will be permitted as long as treatment has been ongoing and stable for at least 3 months prior to randomization

Stimulant medications for fatigue (such as methylphenidate, modafinil, armodafinil, amantadine or dextroamphetamine) will be permitted, but subjects will be asked to not take these medications on study visit days until all study procedures/assessments are completed.
